Ashley Parker Angel's Butt Challenges You To 100 Days Of Fitness

Former O-Town singer (and recently of Broadway's WICKED) Ashley Parker Angel has taken to his very popular Instagram account to issue a challenge. And he's using his considerable ass-ets to get your attention.

You will realize, as you peruse the account, that APA is NOT shy to show off his fitness progress.

Check out APA and his naked butt below. He has my attention.

The #100DaysOfFitness challenge may be behind me now but the journey continues. It's incredible how the human body responds and transforms to even just 100 days of a consistent diet and exercise program. During the last 100 days your positive comments motivated me to push through and stay committed. I encourage all of you to experience for yourself how rewarding it is to set your own goals and get inspired by the results. You don't have to be a fitness model or featured in the ESPN Body Issue to be proud of your physique. We all have what it takes to be the best version of ourselves we can be. Be dedicated, be passionate and be relentless in the pursuit of your dreams. Shortly, you will look back at where you started and be astounded at how far you've come... and you might just be inspired enough to post a naked picture of yourself on Instagram. ✌🏽 #Day100
